To all whom it may concern.:

llc it known that we, PETER here, DON- ALD (fonc, and Emmer L. FinasoLn,citizens of the lnited States, and residents of Can-f ton. in the countyof Stark and State of` (lhio, have invented certain new and usefulImprovements in Ammonia- Compressors; and we do hereby declare thefollowin' to he a full, clear, and exact description of the invention.

The present invention relates to improvements in animoma-compressors,the object of which is to provide means and devices which will maintainthe cylinder cool by the incoming ,gas and at the same time pro videmeans whereby a compound or double action is produced.

With these objects in View the invention consists inthe novel featuresof construction and combination and arrangements of parts which will hemore fully hereinafter described and pointed out in the claim.

In the accompanying drawing: Figure 1 is a vertical longitudinal sectionof the cylinder ilhistratingir our improvements properly arranged withreference tosaid cylin der. Fig'. Q is a sectional View taken on line yFig. 3 is a transverse section taken on line 3HE, Fig. 1. Fig. 4 is aView of the cylinder showing' parts broken away, also showing one of theheads and caps de tached. Fig;A 5 is a horizontal sectional view of thechan'xbered head showing the feed pipes properly located.

Similar numerals ot' reference indicate corresponding parts in all thefigures of the dra wi rigs. l

ln the accomtmnyinpr drawing, 1 represents the cylinder proper, whichcylinder is 'Formed of any desired size, reference being had to thecapacity of the con'ipressor and as shown it is provided with theintegral hase 2, designed to be properly connected to the foundation orhase plate 3.

7Within the cylinder 1 is located the piston rod el, which piston rod isreciprocated by any wellv known and common means. Upon the pistonr #tare securely mounted the pis tons 5, which pistons carry the pistonrings G, said rings areeach provided with the seat Yflanges 7 and thecushion rings 8, but these parts within themselves 'form no specificpart of this invention and we lay no claim l to the specilic anddetailed construction oi,l

thc pistons and their different parts.

Around the cylinder 1 is hicated the chamber fl, which chamber isiaiclosed by the integral casing 10, and the outer Wall of thecylinder 1. lhetcasinpr 10 is provided with the valve connecting 'flange11, to which is connected the valve 12,. said valve being of anyordinary construction and from which valve leads the ordinary 'Feedpipe, which is extended to and connected withthe coils of therefrigeration chambers. rllhis pipe is not illustrated as it will heunderstood that an ordinary feed pipe is to be employed,

lt. will he understood that the gas (pieta temperature as possibleduring the time the cylinder is heini;1 filled andthe gas compressed andhence it is ot' importance that provision he made for maintaining, thecylinder at as low a temperature as possible l and this invention hasmore specific reference in keeping the cylinder at a low temperature.For this purpose of keeping the cylinder at. a low temperature thecentral or intake portion ot' the cylinder covered with a layer ofsuitable insulating mate-rial, such as cork, sawdust or asbestos 13,over and upon which is placed a metallic sheet connected to the casino'1() or its equivalent. The endso the cylinder 1 are closed hy means ofthe chambered heads l5 and 16 to which heads are connected the caps 17,said caps and chamhercd heads being so `arranged with reference to each.other that water can be forced through said chambered heads ashereinafter described, To the'caps 17 are connected the cold water pipes18, which cold water pipes lead to any source of supply and may heprovided W1th cut off valves 19 of any desired construction.v Thechanihcred heads and 16 may be provided with the Webs 20, which webs arefor the purpose of interrupting the rapid flow of water and at the sametime presentintf;- a `greater cooling surface, said webs also servingthe purpose for strengthening the heads.

For the purpose of causing water to enter weh of the wells 20, two pipes21 are provided, which pipes are connected b the cross passage ways 22formed in the cap 17. When the chamhercd head becomes filled with wateror practically so it is conveyed from the hea, hy means of ille outletpipes 2?, located upon opposite sides ot' the upper wel 20 and thenceconveyed to the pipes Q4,

upon opposite sides of the lower or vertical erahly ammonia) should hekept at as 0W l to which pipes are connected the spray pipes 2:. saidspray-pipes being located directly oxr and above the o utcr end portionsof the cylinder' l. jFor the ,purpose oi causing the water to iliow i'na sheet erlfeitream of a width practically equal to the length of thepipes 25 the escape or over low slots 26 are lo` cated in the top orupper sides of the pipes For the purpose of removing the water after ithas performed its function the drain pipes 27 are provided7 which drainpipes lead to any desired place. For the purpose of observing theoverflow of the water, the pipes 27 are provided with the open sidedcouplings 28, which open sided couplings provide over-flow passages ifthere should be any backine up of the water. For the purpose ofcollecting the water thatV passes from the pipes 25, the ianges 29 areprovided, which fianges retain the water and guides the same to thedrain pipes 27. Between the pistons 5 and through the shell of thecylinder l are formed a series of intakerv ports or passages 30, throughwhich the gas passes into the cylinder and as the pistons are moved backand forth or reciprocated the gas will be compressed and forced throughthe valves 3l and thence conveyed through the pipes 32 to thecondensers. The pipes 3Q are or should be provided with the ordinaryvalves 33. It will be understood that aiter the gas has been thuscompressed it is in a heated condition, hence the necessity of returningit to the condensers. The valves 3l are so constructed that they will beclosed except'at such times as the pressure is sufficient to overcomethe tension of the springs 34, and the back pressure, at which time thevalves are open.

It will be understood that by forming two pistons and mounting them uponthe piston rod,^and locating the intake ports between the pistons thegas will be compressed alternatelyat the opposite ends of the piston,thereby producing practically continuous compression. In order that thegas may pass through the pistons 5A during What might be termed theirbackward or idle strokes the piston rings 6 are so connected that therewill Le a slight relative morement as between the pistons proper and therings thereby allowing the seat flanges to be disconnected from the seatfaces of the pistons,

In Fig. 1 the piston rings are shown seated and unseated or in otherwords the pistons closed and opened. This feature however fornis nospecie part of my invention except that it is necessary to providepistons that will l1iot compress the gas during their backward or idlestroke.

It will be understood that liquid and sediment will accumulate from timeto time and settle in the bottom of the chamber 35 and for the purposeof removinv this the stop cocks 38 may be provided. letween` the extremeend portions of the cylinder-1 and the central or what might be termedmiddle portion of said cylinder there ,are spaces that will not becomeheated as rapidly or to -as high a degree as the outer end por tions andhence it is unnecessary to provide any means for cooling saidparts'other than atmospherically cooling' and hence the pipes` 25 arenot necessarily extended to the ends of the middle or ipsulated portionof the cylinder.

It will be understood that the pipes 25 should be protected and hiddenand inorder to provide for this the casing 3G is provided. For thepurpose of providing easy access to the pipes 25 the casing 3G should beprovided with the removable-covers37.

Having fully described our invention what we claim as new anddesire tosecureI by Letters Patent, is-

In acompressor of the class described, a-

eylinder having a chamber extended vfor a portion of its length, intakeports'formed through the cylinder, said chambered portion of thecylinder provided with insulation and portions of said cylinderatmospherically exposed, chambered heads provided with webs adapted toclose the ends of said cylinder, water pipes leading to and from thechambered heads1 a piston rod 'and piston located thereon, said pistonadapted to open and close. substantially as and for the purposespecified. In testimony that we claim the above, we have hereuntosubscribed our names in the' presence of two witnesses. i' PETER NEFF.DONALD `COLE. ,l ELBERT L. EBERSOLE,v` f Witnesses: Y
